Specification of Letters Patent.

Application filed April 4, 1918. Serial No. 226.579.

7 o ((11% i1 0m '1' i may concern lie it known that l, Ennswon'rn A. llniv- 'rnonnn, a citizen of the. United States, and a resident of lilridgeport, county of Fairficld, and State of Connecticut, have invent ed an Improvement in Electrical Gonnec tions, 01": which the following description, in connection with the accompanying dre\vings, is a. specification, like characters on the drawings representing like parts.

This i vention relates to electrical connections, and is more poreiculerly concerned with a battery connector for connecting; together the terminals of two or more butteries.

My invention will be best understood by reference to the following description, when taken in connection with the accompanying drawings of one specific embodiment there-- of, While its scope will be more particularly pointed out in the appended claims.

In the drawings:

Figure 1 is e. phtn of two batteries equipped with a connector embodying my invention;

Fig. 2 is a. detail sectional view on line 2--2 of .l ig. 1;

Fig. "l is a detail sectional View on line 3--3 oi Jig. .1;

11 l is :1. detail sectiona view on line A i of Fig. 1;

Referring to the drawings, and to the embodiment of my invention which is illus- .trzited, I have there shown two batteries 7' and 8, herein common dry cells, the battery 7 being provided with usuhl:threaded. terminals or binding p sts 9 and 10, and the bat-- tery 8 being provided With'siniilhr terminals or binding posts 11 and 12, as best shown in Figs. 2 and As usual in dry' cells of this type, the terminals 9 and 12 are while the terminals 10 and 11 are disposed adjacent the peripheries of their resp -tive cells.

As a. incqms for holding the batteries in proper relation with each other, and to prevent twisting and displacement or the conducting Wires, as Well as to avoid the p0ssibility of short circuits, 1 have provided an insulator 13, which may be and is herein in the form of a sheet of insulating material, provided with a plurality of termhml-receivin; apertures 14k, 15, 16 and 17, to receive the battery terminals. The insulator acts not only to maintain the batteries in proper relation with each other, but else serves as best shown in liig. 1.

n mounting for a terinimil-eoiniecting eonductor 18, which verlies the plate and is preferably secured thereto in some nppro printe numb-e. in the present cxziiiinle. said coinlnctor is prorided with inteogrel tin bulerhistcners l9 and 20, snown in l 9,, which may bet'orn ed by punching ho. in the conductor and riveting or heeding the metal over, cleorlv shown in to form tubular rivets. hose hollow listeners then constitut il-receiving openings.

Any suitable rnenns they be einpl jived to secure the conductor 18 to the terminals ll) and. 12, but in the present example, 1 have shown nuts 21. end threudeu G1 o seid terminals, and preferably provided ith insulo ting shed" s 23 and 24s, respect" i.y,vvliicli may be conveniently molded OiitO said nuts. Similar nuts and 26, best shown in Fin. 3, and also preferably provided with insuletingshells 2'? and are threaded onto the terminals 9 and '11 res n-active y. 'llhe nut may serve to secure the insulating plate 13 to the terminal 1'3, Well as to cure to the letter at usual conducting wire 2%), which may have a usual terminal 30, 7 Similarly, the nut 10 secure the plate to the terminal l2, es well as to secure to the hit-- ter n conducting wire ill having a suitable terminel 32.

Yrs/terribly the nut 26 is 'pillnfiile'fltly joined to the terminal 32 by being mounted to rotate thereon, so that it cannot be ucci' dentally detached therefrom, but may he rotated for the purpose of attaching the to the term l 12. To this end, I have. provided the nut E26 with a hollow shank best shown in Fig. 3, extending through in opening;- 34: in the terminal 32, "and headed over to :1 sufiicient extent to hold the parts pern'uinently attuched, While permitting one to rotate on the other. The nut "is at tnched to the terminal 30 in like manner.

As it means to prevent rotation of the terminal 352, I have herein provided a. conductor-receiving gnerd. 35, best shown in Fig. 4, through which the conducting Wire 31 and its terminal 32 extend, as best shown at the right-hand side 0t Fig. 3. This guard may be secured to the plate 13 in any eppropriete manner, as by providingsuch guerdnvith a pair of prongs 36, extending through said pleteend bent over, as clearly shown in Fig. 4. It should be evident that by this inc-ens, the Wire and its terminal are 26 niav held in proper position, and prevented i'i turning or interfering with the other conductors.

The insulating plate l3 may be of any suitable shape, but in the form shown in Fig. 1, the same is rhomboidal, -that is to say, it is a non-rectangular parallelogram. This is the form best suited to a connector having four termirial-receiving apertures, since each of the i'our'corners provides a convenient location for one of the apertures.

Having thus described one embodiment of my invention but without limiting myself thereto, what I claim and desire by Letters Patent to secure is:

l. The combination of two batteries, each provided with a pair of terminals, and a battery-connectlug ii'isulatine' plate having four sides and four corners and provided with tour terminal-receiring pertorations one adjacent each of said corners.

2'. The \':onibination of two batteries, each provided with a pair of terminals, and a l. atter v-connc ting insulating plate having four sides and four corners, two of said sides being at an obtuse angle to each other, said plate being provided with tour terminalreceivine perforations one adjacent each of said four corners. v

3. The combination of two batteries, each provided with a pair ot terminals, and a batterya-onuecting'insulating: plate having four sides and tour corners, and having a generally rlioinlmidal shape. said plate being provided with tour terminal-receiving peri'orations one adjacent each of said four corners.

L. In a battery connector, the combination of an insulator provided with a plurality ot terminal-receiving apertures, a conductorreceiving guard associated with one of said apertures. and a termirial-connecting conductor associated with two of said apertures.

:i. In a battery connector, the combination of an insulator provided with a plurality of ternnnal-receiving apertures, a conductoral-connecting conductor associated with two of said apertures.

6. In a battery connector, the combination of an insulator provided with a plurality ot terminal-receiving apertures, a U-shaped conductor-receiving guard associated with one of said apertures and provided with a pair of fastening prongzs'extending into said insulator, and a terminal-connecting conductoassociated with two of said apertures.

T. In an electrical connection, the combination of an insulator provided with a termiual-receiving aperture, a cornluctorreceiving guard associated therewith, a conductor extending through said guard and held thereby against rotation, and a thread ed conductor-fastener attached to and mount-- cd to rotate on said conductor.

8. An electrical connection comprising, in combination, a conductor provided with an aperture, and a threaded. conductor-tastener attached to and m unted to rotate on said conductor.

E). An electrical connection comprising, in combimltion. a conductor provided with an aperture, and a conductor fastener extending through said aperture and provided with a scre\\'-thread for attachment to a terminal.
